Default DIY drivers?

Does anyone make their own drivers? It seems like many of us could handle the magnet, mounting, winding the voice coil. Making the cone could be an issue.

Just wondering. Compared to some of the projects around here, building a driver doesn't seem like a big deal.
Ive seen a few videos online of people making their own tubes/valves! That seems more complex.

I was just looking at drivers, and saw some 12" for over $1000, and they looked quite hand made.

Just curious........

There are (some) people building their own speakers and discussing patents/and secrets on line, like the best pulp mix or nano carbon film for paper/other cones. You just have to look for it.

There's also a variety of technologies on Loudspeakers if you know what you are looking for:

I believe the testing of the drivers would be the most important
part of any manufacturing process.

Qes, Qms, Qts, SPL, Le, Vas, fs etc, etc.

If I ever seriously considered building my own drivers I would
cost an oscilloscope, frequency counter, sine wave oscillator,
quality measuring meter, then take an electronics course & learn
how to use them. Then I would take an extended maths course.

Sounds simple enough

Hopefully anyone building an amp has a scope, and who doesn't have a sinewave osc? (music synth, pc, etc)
If there was a community doing such things, you wouldn't have to figure out all of the technical details on your own.

But I get your point.
I'll take that as basically a "no" to my original question.

It is actually something that I have given thought to, as I like coming up with my own ideas and designs for various things. I have often thought about making my own drivers, and thought about different methods of construction etc.
I once started planning a woofer that used the tuned enclosure as the actual frame for the unit, as well as some other bizarre designs, as well as home made magnet structures etc. I have yet to build any drivers, but I will sometime. I also have taken bits from different drivers and combined them, often just from different drivers that have problems to make one good one.
I just seem to like mucking around and experimenting with different things.

Yes
But I had decided on an OB mid, so no issue there
I still need to do the chassis
The cone is the easy part

The other day I thought it could be fun to try a small underhung cone tweeter with huge magnet

Hi tinitus,

I remember seeing that picture quite a while ago. That's a really beautiful cone!

How about the rest of the driver? I'm so interested in all those details (I believe many others are, too). Please share more info if you can.

Thanks a lot,
CLS

I remember a chinese diyer who posted his pics two years ago , but I can't manage to find the link between 850 pages in the forum.
He attached long cones to headphones motors , probably rice paper , and was happy of the sound . Indeed they were beautiful art works , where chinese tradition in paper processing was shown . Does anybody remember him ?

Hi Tinitus,

I cannot mail you via DIYA so please drop me an email. I might have some information for you regarding the special type of cone you have made.

Kind regards

Karsten
